This NOAA site will no longer provide GOES-East imagery. For access to high resolution GOES-East imagery from GOES-16, please go to the site: We apologize for the inconvenience and appreciate your patience.


Effective 1200 UTC November 16, 2015, the NESDIS Satellite Analysis Branch (SAB) Satellite Precipitation Guidance Message Product (SPENES) will no longer be issued for the continental US (lower 48 states). SAB will continue satellite support to WPC and satellite-based information from SAB may be integrated by WPC's forecasters into their MPDs (Mesoscale Precipitation Discussions). This is intended to provide a single source of centralized guidance on heavy rainfall and flash flood threats and ensure consistent message delivery. More information about the MPD is available at:

QMORPH Information

Sample QMORPH Graphic

"QMORPH" is a variation of the NOAA Climate Prediction Center Morphing Technique ("CMORPH") that uses precipitation estimates derived from low orbiter satellite microwave observations exclusively, and whose features are transported via spatial propagation information that is obtained entirely from geostationary satellite IR data. Instantaneous precipitation estimates derived from the passive microwave sensors aboard several polar orbiting satellites are combined to create the CMORPH and QMORPH datasets. Note that this technique is not a precipitation estimation algorithm itself but a means by which estimates from existing microwave rainfall algorithms can be combined.

IR data are used as a means to transport the microwave-derived precipitation features during periods when microwave data are not available at a location. CMORPH uses two microwave passes over a given location to interpolate precipitation estimates forward and backward in time while QMORPH only uses one microwave pass to interpolate the precipitation estimates forward in time. Because of this difference in the two products, QMORPH is available about 3 hours after real-time while CMORPH is available about 18 hours after real-time.

The NOAA/NESDIS Satellite Analysis Branch uses the GRADS display program to add up QMORPH estimates over specified time periods. These estimates are being provided experimentally and on an as needed basis as determined by the analyst as a supplement to the Satellite Precipitation Estimate (SPENES) text messages.
